I have a damaged (hole) in the filter of the petcock. Unable to find a replacement of the filter (I tried Bikerbandit.com and Powersedge.com) I decided to replace the petcock. Since most petcoks do not fit ( the filters are usually round and larger) I will have to make adjustments to the tank. Also, the vacuum line is eliminated. I assume I just plug up the connect to the carburator (?). Has anyone tried this? What brand/model petcock did you use and how was it installed? Will it work by just plugging off the vacuum line? I am at a loss as to what to do. Thanks for any help
